\ CAR CONSTRUCTION Filed Dec. 19, 1929 key slot 24 of the pin A and one of the pairs of alined slots of the sleeve B. As shown in the drawings, the key is engaged within the pair of .slots 2828. As will be evident,

when the sleeve is turned with respect to the pin member A, either of the other two pairs slots will effect elevation of the lower end of the pin and bring the head 23 thereof closer to the shoulder 21 of the truck bolster, thus shortening the effective length of the pin. This adjustment is important to take up for wear which occurs between the parts. The key C is of such a length that it extends through the slots 2727 in the wall of the pocket 25 and projects some distancebeyond the wall at the righthand side of the pocket, as viewed in Figure 2. Accidental removal of the key C is prevented by a retaining bolt 31 extending through the projecting end of the key and through alined vertical slots 3232 provided in spaced webs 3333 on the body bolster, as clearly shown in Figures 1 and 2. Upon reference to Figure 2, it will be seen that the slots 27 -27 are of considerably greater height than the slots in the sleeve B, thereby permitting vertical displacement of the key in making the different adjustments. The slots 3232 of the webs 33'33' accommodate upward movement of the bolt 32 for this adjustment of the key; In order to support the pin on the truck bolster, a shelf 34 is preferably provided. This shelf is in the form of a flanged plate having horizontal section on which the head of the bolt rests, and spaced vertical sections in the form of flanges at opposite ends thereof which are riveted to the webs 20 20 of thetrnck bolster. In applying my improved combined locking and center pin means to the bolsters of a railway car for connecting the same, the pin A is inserted upwardly'through the opening of the truck bolster into the body' bolster. When the pin has been completely inserted,'the shelf 34 may be applied and riveted to the webs of the truck bolster, The sleeve Bmay then be placed within the pocket of the body bolster about the upper endof the shank of the pin with the proper pair of slots alined with the key receiving opening of the 'pin and the slots27 27 of thebody bolster so as to obtain the desired adjustment in lengthof the pin. The key, C is then inserted through the alined slots of the sleeve and pinzmemb ereA by entering the same through one of the openings or slots 27 of the body bolster; After having been engaged within the slots, the key is secured against removal by theretainer 130113131. t I, V i I s a In this connectionyit is pointedqut t in assembling the parts of the combined locking and center pin members with the bolsters, the sleeve B maybe inserted within the pocket of the body bolster before the pin A is entered through the opening of the truck bolster. It is further pointed out that the shelf 34 need not necessarily be employed and that the parts may be assembled by first placing the sleeve B withinthe pocket 25 of the body bolster, then entering the pin through the opening of the truck bolster and immediately engaging the key C within the proper openings of the sleeve B and the the pin A. When it is desired toseparate the bolsters, it is merely necessary to remove the key 0, whereupon the body bolster may be elevated with respect to the truck bolster. In case it is found necessary to remove the pin, the shelf 34 is detached and the pin dropped through the pin receiving openings of the bolsters after removal of the key C.

' The adjusting sleeve B provides for six different adjustments. The three sets of slots being spaced different distances from the top and bottom ends, the sleeve may be reversed or inverted end for end,,thereby obtaining three adjustments when i in the position shown in Figure 3 of the drawings and three additional adjustments when inverted.

I have herein shown and described what I now consider the preferred manner of carrying outnny invention, but the same is merely illustrative and I contemplate all changes and modifications that come Within the scope of the claims appended hereto.

I claim:

1. In car construction, the combination with body and truck bolsters provided with alined center pin receiving openings; of a center pin extending through said openingsand having shouldered engagement at one end with one of said bolsters to prevent removal of the pin inone direction; and means extending through the free end of the pin and bearing on an adjustable member having shouldered engagement with the other bolster to prevent removal of the pin in the opposite direction. I V

'2. In car construction, the combination with body and truck bolsters provided with alined center pin receiving openings; of a solid center pin extending through said openings,said pin having a head at one end, the head having shouldered engagement with one of the bolsters to prevent removal of the pin in one direction; a removable key extending through the opposite end of the pin; and an adjustable member surrounding the shank of the pin interposed between the key and an abutment surface on the other bolster, thereby preventing removal of the center pin in a reverse direction, said adjustable member having shoulders at different elevations with which said'ke member is engageable to effect adjustment of the pin to compensate for wear.
